| Abstract: A diagnostic algorithm is proposed to derive and model the ionosphere parameters modified by powerful high frequency (HF) radio waves. The proposed model is composed of three steps: characterization of the HF ionosphere heaters in terms of location, effective radiated power, frequency, and operation modes parameters, diagnostic of the ambient ionosphere parameters, and simulation of the effects of the heating experiment on the ionosphere. The proposed algorithm is applied to investigate the artificial ionospheric irregularities and instabilities produced by HF heating experiments reported from different ground-based HF heating facilities such as HAARP at Alaska, and EISCAT heating facility in Tromso. The ionospheric instability and irregularity parameters are then derived from the measured modified ionospheric parameters during heating experiments. The conditions for the hydrodynamical equilibrium disruption and initiation of the artificial aurora are derived and discussed in terms of the HF heating facilities parameters. | ||
